Shah et al.used Reddit to gather \(7,098\)  English posts. The dataset consisted of \(3,549\)  user-posts containing suicidal ideation taken from a sub-Reddit called SuicideWatch and labeled "1". A further \(3,549\)  pieces of data of different popular Reddit posts that do not contain suicidal ideation and labeled "0"are also included [1]}. The dataset consists of 594 suicidal ideation tweets out of \(10,288\)  tweets using a keyword filtering technique including suicidal words and phrases such as, e.g., suicide, die, and end my life. The text is then manually annotated to Suicide, Nonsuicide text [2]}. Questionnaires are also considered textual data sources. Jain et al. used two datasets, one from questionnaires and the second is from Reddit and Twitter and a labeled dataset from Kaggle [3]}.
